The rapid development of science, industry and mechanical engineering allows you to quickly and reliably build industrial facilities and residential buildings.
During construction, it becomes necessary to raise to a height or move steel and concrete structures, tanks and reservoirs, as well as blocks of equipment and special equipment.
Only a few companies can produce machines capable of handling loads weighing more than 1000 tons.This task is taken on by modern - the largest truck cranes in the world. Let's analyze several models of truck cranes - champions, by the way, among them there are 3 manufacturers from the People's Republic of China, and one representative from Germany and the USA each.
Rating of the largest truck cranes in the world
Truck cranes are among the. On the 5th place is the machine of the American company Terex-Demag - model AC 1000. It is able to work in harsh climates and move on bad roads.

The manufacturer equipped the autocan with 4 engines different power(150, 260, 430 and 650 hp).
Such giant machine will work in the construction and installation of chemical and metallurgical enterprises. The release of the novelty, recognized as the most lifting and high-altitude truck crane in the world, was timed to coincide with the 20th anniversary of the formation of Zoomlion.
Summarizing
IN this review of the five most powerful truck cranes, three are represented by companies from the People's Republic of China. In 5 years, Chinese firms will take a leading position in many segments of the world market, which suggests that we need to take a closer look at the products of Chinese industry and, in matters of import substitution, focus not on the West, but on the East (China).
The LTM 11200-9.1 is the most powerful telescopic boom crane in the world and its boom is the longest of the telescopic booms. Self-propelled boom crane with telescopic boom mounted on a special nine-axle chassis automotive type. He is the highest and most powerful crane in the world.
"Mammoth" can lift a load of 1200 tons to a height of 180 meters. There is no crane in the world capable of handling such a task. The extension of the 8-section boom to the required length and fixing it to the clamps is fully automatic. Additionally, various lattice extensions are available. Germany is the birthplace of the world's largest mobile crane.
The Liebherr LTM 11200-9.1 is 30 times more powerful than a conventional mobile crane. Parts for the assembly of the "Mammoth" are delivered to the site of the planned work on twenty trucks, accompanied by a convoy. The weight of the load and the weight of the crane itself are distributed over 4 hydraulic legs - 200 tons each. Iron supports are placed under each paw to distribute pressure. This is very important point, because if the support moves and the crane falls, this will lead to huge destruction. The crane arms are equipped with huge cables, which gives the machine even more strength. A huge counterweight system is located under the crane boom - 18 plates weighing 10 tons each are placed on a base weighing 22 tons. The crane is mainly used to install heavy loads, such as wind turbines. The length of the crane hook on the Liebherr LTM 11200-9.1 mounting block is almost 10 meters, and it weighs 11 tons.
The crane mechanisms are controlled from the control cabin, which is made of a fibrous composite material with the possibility of hydraulic adjustment in height and angle. Installed in the control cabin electronic system controls with LICCON type equipment. All chassis wheels have two braking systems: pneumatic dual-circuit with disc brakes and a ZBS type engine brake system with free release valves.
However, an unpleasant incident occurred with the LTM 11200-9.1 crane during the installation of one of the wind turbines in Germany due to a sharp gust of wind, the crane boom collapsed, but the crane itself remained on the move and, fortunately, no one was injured.

The working special transport LTM 11200-9.1 can be called the largest truck crane, which is popular all over the world. It is equipped with the longest retractable telescopic boom among similar types of equipment and is a unique development of German manufacturers.
This special equipment can lift and move various cargo masses, the weight of which is 1200 tons with a reach of the boom device equal to 2.5 meters. This task is too difficult for the rest of the cranes produced on the planet.
The most powerful telescopic truck crane
The largest truck crane, the best in the world in terms of its lifting characteristics, has a retractable boom 18.3-100 m long, with a unique lattice extension, the length of which can be 24-126 meters. A similar special transport, activated by an 8-cylinder mounted on the chassis diesel engine Liebherr, running on a diesel fuel resource and equipped with a turbocharger, the power of which reaches 500 kW or 670 hp.
The crane installation is powered by a 6-cylinder engine of the same company with a capacity of 240 kW, operating on diesel fuel. The truck crane moves at a speed of up to 75 km/h and has a mass, together with a counterweight, of 202 tons.
The Liebherr LTM 11200-9.1 is 30 times more powerful than a conventional crane. The components from which it is assembled are brought to workplace 20th trucks, after which the crane is going to general design and ready to work for eight hours.
200 tons of crane weight and its working load are distributed to four paw pores, working on hydraulics. To distribute the pressure under each of these support devices, it is necessary to place platform supports made of thick iron. If the supports move, the crane may fall, which will lead to great destruction and complete failure of the equipment.
Characteristics of the Mammoth wheeled crane from the German company Liebherr
The booms of the largest truck crane in the world have strong cables that increase the power of the machine. Beneath the crane boom is a large counterweight system with 18 plates on a 22-ton base, each weighing 10 tons.
When lifting different loads, the supports are subjected to quite a lot of pressure, so it is necessary to observe low speed this process. The truck crane control cabin contains monitors, where information about the magnitude of the load on each part appears.
The operation of the crane is controlled by operators who monitor the accuracy of operations, preventing backfire errors. LTM 11200-9.1 is used during the construction of bridges, telemasts, high-rise structures.
This unit can also load and unload equipment with large dimensions, and other types of special equipment. In addition, this crane machine is used during the construction of military experimental facilities, and costs 14 million dollars.
When might a specific and unique 500 ton truck crane be used? This large technique can only be used on giant objects with heavy structures that can not be moved by equipment with a small load capacity.
The largest truck cranes, which have gained worldwide recognition, allow the transfer of fairly heavy loads, have an increased value of cross-country ability, maneuverability and cruising speed. These advantages force road construction organizations to purchase this special equipment.
These cars mobile cranes are so expensive that it is impossible to acquire ownership and fully maintain them, so many companies consider renting a 500 ton truck crane the most the best remedy for use in a variety of construction sites.
Huge mechanisms always attract the attention of people, because it is not possible to meet a crane the size of a high-rise building every day. Modern truck cranes are capable of lifting loads weighing more than a thousand tons. Consider in this article the heaviest and lifting of them.
There are some differences between tower, truck and crawler cranes.
Towers have a lower carrying capacity than automobile and caterpillar ones, but they are the most commonly used mechanisms during construction work. Automobile, in turn, are capable of transporting cargo, and also do not need to be disassembled.
The largest tower cranes
One of the biggest tower cranes is the Kroll K-10000, manufactured in Denmark since 1978. Its maximum load capacity reaches 360 tons, and total weight is - 880 tons. The height of this giant is 143 meters, and the reach of the arrow is up to 84 meters.
There are options with a lower maximum reach - 64 meters. The range of the Danish company also includes an auxiliary crane K-355, which has a lower lifting capacity. It is used for basic installation and other auxiliary work. During transportation, the crane is dismantled, and the transportation itself requires a special railroad. Then it is installed on a concrete foundation next to the building under construction. Installation and dismantling last about 3 months. In the past, K-10000s were used mainly in the construction of nuclear power plants.
It is necessary to mention tower crane Wilbert WT 2405l e.tronic with lifting boom which allows you to lift heavy loads to great heights. The minimum and maximum outreaches are 36 and 78 meters respectively. It has a height of 128 meters, however, it can be increased with the help of special tower sections. The maximum lifting capacity of the crane can reach 128 tons, while the speed of lifting and transporting cargo does not suffer. The operator's cab is very comfortable, visibility is provided by two monitors and 9 wide panoramic windows.
Another crane of interest in the special equipment market is the Wolff 1250B, manufactured in Germany. It is often used to build power plants. Wolff is capable of lifting a load of 60 tons. The maximum radius of the boom has a length of 80 meters, at this distance the load capacity is reduced to 11 tons. To increase the length of the boom, sections of 5 meters are used. The advantage of the model is the working height of 90 meters, which is a very good indicator for tower cranes of this type.
The largest truck cranes
Truck cranes confidently push back tower cranes, as they have a number of advantages. First of all, they are more mobile, they do not need to be assembled and disassembled, moreover, they themselves can carry various goods. Secondly, due to the design features, due to which the heaviest truck cranes have a lifting capacity of up to 1000 tons or more, their popularity is growing more and more.
The German Liebherr LTM 11200-9.1 at one time had a record lifting capacity of 1200 tons, and its 100-meter telescopic boom was considered the longest. To lengthen the boom, 6 and 10-meter sections were added. Lifting boom, her maximum angle goes up to 86 degrees. Max Height crane lifting is quite impressive - 180 m. But at this height, the truck crane is able to withstand a load weighing no more than 1.3 tons.
The Chinese company XCMG, specializing in the production of special equipment, has released its XCA5000 truck crane. Max load, which he can lift, about 1600 tons. One of the features of this model is the ability to move sideways and "crab". He develops top speed 80 kilometers per hour, and thanks to its small dimensions, it is allowed to travel on roads common use. The length of the boom is 105 meters, however, with the help of sections it can be extended to a record 165 meters.
The truck crane of the largest Chinese company Zoomlion ZACB01 in 2015 was recognized as the largest in the world. Its maximum carrying capacity reaches 2000 tons, and its weight is 69 tons. The telescopic boom has a length of 106 meters. The Zoomlion was built on a 12-axle all-wheel drive chassis. The truck crane is equipped with 4 engines of different power (150, 260, 430 and 650 hp). The release of the novelty was timed to coincide with the 20th anniversary of the company's founding. Thanks to its development, Zoomlion got into the Guinness Book of Records.
The largest crawler cranes
Crawler cranes are rightfully considered the heaviest and most lifting. They lift loads with a record weight of 3000 tons, which no tower and car models. This segment is currently dominated by Chinese manufacturers.
The Chinese company Sany in 2011 introduced its crawler crane SCC86000TM, which became "the world's No. 1 crane." He calmly lifts loads weighing up to 3200 tons. Just a year later, another company, XCMG, released a similar model, the XGC88000, which broke the lifting capacity record by lifting 4,500 tons. The crane is equipped with a 60m main boom that can be extended up to 156m with additional lattice sections. The maximum boom height reaches 96 meters.
Closest Competitor Chinese manufacturers- This is the German Liebherr LR 13000, lifting up to 3000 tons of cargo. The maximum lifting height is 245 meters with an outreach of 196 meters. It is quite popular and in demand in the oil refining industry.
From year to year construction works are becoming more complex, the requirements for carrying capacity are increasing, and the equipment is becoming more powerful. It is clearly seen that Chinese companies are seriously taking up the development of not only cranes, but also other types of special equipment. In the special equipment market, each of the listed companies represents several different models for individual segments that differ in many ways. Given the market and technology development trends, most likely in a decade we will see giants of special lifting equipment capable of lifting more than 5,000 tons.

With and without flaws - not produced in Russia
Cranes with a lifting capacity of 600 tons belong to powerful machines, but there are currently cranes in the world whose lifting capacity reaches several thousand tons, the most powerful supercrane has a lifting capacity close to 7 thousand tons.
Most supercranes fall into two categories: fixed with a large slewing ring base and mobile crawler cranes. Both types of cranes have their advantages and disadvantages.
Swivel, which boom structure together with the counterweight, it turns along a rounded rail track, they are stationary, but they have a large load lifting height and reach. The disadvantages of such cranes include the fact that they cannot move with a load, and their installation requires a prepared soil base and even a foundation.
Crawler cranes are easy to move both on the site and from one site to another and can move with a load.
Outrigger cranes such as those made by VersaCrane have the advantage that the bearing capacity of the subgrade can be lower than for other supercranes without outriggers, making them easier to set up on the job site.
Transportation
Transportation of supercranes is one of the important problems that manufacturers solve already at the design and development stage. Thus, Mammoet designed PTC cranes for delivery in containers on ships, these containers then become a ballast box for the crane. The user is instructed to fill the box with local gravity materials - sand and gravel to obtain the design counterweight.
Lampson breaks down its crane structures to fit on 100 trucks, and the boom sections are not welded but assembled on pins.
Parts of the Bigge Super Crane are placed on 160 trucks.
Purpose
Supercranes are used for the installation of large-block, heavy equipment at nuclear power, petrochemical, metallurgy and other construction sectors. IN last years taps with heavy regime work began to be actively used for the installation of equipment for wind power plants.
Of the 13 most big cranes in the list (see table) - 9 cranes were introduced to the market for the first time over the past six years, in this short period the maximum lifting capacity of cranes increased from 2 thousand tons to more than 6.8 thousand tons.
Even 10 years ago, the TC-36000/1 crane with a lifting capacity of 2,268 tons, developed in the USA by VersaCrane, was unique; today it ranks 9th in terms of lifting capacity. Since then, many super cranes have appeared in the category of the most popular lifting capacity of 3 thousand tons, which are mainly used in the construction of nuclear power plants. True, after the accident in Japan in 2011 at the Fukushima plant, the construction of new nuclear power plants in the world slowed down, and the demand for supercranes for these purposes decreased accordingly. But for new generation stations, such as the Westinghouse AP1000 station in the USA, such cranes will be in demand.
